According to an article I read: Pre-inauguration festivities will begin at 9.30am (1.30am, January 21 AEDT) before opening remarks around 11.30am (3.30am AEDT) and the official swearing-in at midday (4am AEDT).

Is Trump gonna let the music play for 3hrs before making his move, probably. I do have work the next morning, so was probably going to wake up at 3am and see what happens live, who's with me?
